LM shaft is manufactured by the advanced process of fine cold drawing, fine grinding and high precision polishing, conforming to or above relevant national standards and specifications for various technical indices.

Normalizing: It refers to the heat treatment process that steel parts are heated 30-50℃ over the critical temperature, and after certain time of heat preservation, the steel parts are cooled under immobile air condition.

In comparison with 304 stainless steel, 316 steel has lower content of Cr, and higher content of Ni and Mo (2%-3% higher), thus it has higher corrosion resistance and is applicable to chemical and seawater environments.

Honed tube is a kind of pipe that the inner hole of cold drawing pipe is machined by honing head with the high speed grinding process, so that the inner hole achieves the tolerance dimension and surface roughness requirements required...
